#Running Behat Tests using Chrome If you would like to run Behat Tests using Google Chrome here are a few steps I went through to get that setup.

1. Download the Google Chrome Webdriver

2. Unzip the file, and place the chromedriver file in a known location.

3. Now edit the behat.yml file and create a new profile for using Chrome by adding the following below the default profile.

      default_session: selenium2
      javascript_session: selenium2
      goutte: ~
      selenium2:
        browser: chrome
    SilverStripe\BehatExtension\Extension:
      screenshot_path: %behat.paths.base%/_artifacts/screenshots

4. Now we need to use the new webdriver with Selenium.

java -jar selenium-server.jar -Dwebdriver.chrome.driver="/path/to/chromedriver"

5. Now run your behat steps with the chrome profile.

behat @mysite --profile=chrome
